Hawk attack--Gaping wound--Maybe shock

Several hours ago, a large hawk attacked my Khaki Campbell duck. I chased the hawk off before she could do a lot of damage, but the duck took a beating.

She is injured in at least three areas (head, neck, and leg). There are a small to medium gaping wound on her leg under her feathers. It is not large, but it is gaping.

I immediately bathed her in Oxine treated water, then put antibiotic ointment gel thickly on her wounds.

She is currently in a dog kennel with fresh straw, clean water, fresh feed, and a bowl of scrambled eggs with cheese and ground beef (I wanted her to get a lot of protein). I cannot tell if she has eaten or had water yet.

After setting her up in clean surroundings, I had to leave for a meeting. She was alone for about 2 hours. I just got home and checked on her and she was lightly panting and slightly shivering.

My concerns are:

Could she be in shock, and what is the best way to treat for shock?

There are flies around her, how to I best protect her wounds from flies?

If I allow her to be in the same area or free-range with the chickens,won't the chickens attack her because she has bloody areas?

Right now it's in the mid-70s. It was an insane 80-degree day. But a cold front is coming in tonight. By midnight, we'll have 30-mph winds and it will freeze tomorrow. Yes, we're getting a 50-degree drop. The shed is a great idea.
